Extending representations of claims.
So far the representation of the claim \(\textbf {c}\)  (Eq. REF ) is only from textual content. In reality, a speaker who made a claim may impact credibility of the claim. For example, claims from some politicians are controversial and inaccurate [1]}. Therefore, we enrich vector \(\textbf {c}\)  by concatenating it with speaker's embedding \(\textbf {s}\)  to generate \(\textbf {c}^{ext} \in \mathbb {R}^{x}\) , where \(x=2H+D_1\)  as shown in Eq. REF .
\(\textbf {c}^{ext} = [\textbf {c};\textbf {s}] \in \mathbb {R}^{x}\)
